How to check the battery status on the Xiaomi phone: all the ways

Why it is important to monitor the battery status of Xiaomi

Modern Xiaomi, Redmi and POCO smartphones are equipped with lithium-ion batteries that inevitably degrade over time. Even if you buy a new device, after 1-2 years of active use, the battery capacity can decrease by 15-30%. This leads to rapid discharge, sudden outages and charging problems. But how exactly do you know what condition your Xiaomi battery is in?

In this article, we’ll look at 7 proven ways, from hidden engineering menus to third-party apps, how to test battery wear without root rights, what the numbers mean, and when to think about replacing your battery. And why some Xiaomi models (such as the Redmi Note 12 Pro+ or POCO F5) may not work standard methods — and what to do about it.

Spoiler: If your phone runs out in half a day with moderate use, the problem isn't always the battery, sometimes it's background processes or unoptimized software, but it's hardware degradation that you need to rule out first.

Method 1: Checking with code ##4636##

This is the fastest way to get basic battery information, but it doesn’t work on all Xiaomi models. Enter the combination in the Phone app:

##4636##

If the code worked, you'll see the Test menu. Go to the Battery Information tab. Here you'll see the key settings:

• 🔋 Charge level – current percentage in real time.
• 🔌 Power supply: Battery (from battery) or USB/AC (charge-free).
• 📊 The state must be good (good) or unknown (unknown).
• 🔢 Temperature - optimally 25-40°C. Above 45°C - overheating!
• ⚡ Voltage is the norm for Xiaomi 3.7–4.4V.

⚠️ Attention: New models with MIUI 14+ (for example, Xiaomi 13T or Redmi K60) This code can be blocked. If nothing happens after you type in, move on to the next method.

💡

If the ##4636## code doesn’t work, try the alternative combination for Xiaomi: ##6484## (MIUI Battery Info).

Method 2: Hidden Engineering Menu (MTK and Qualcomm)

A deeper diagnosis can be done through the engineering menu, but there are nuances here depending on the processor of your Xiaomi:

• 📱 For smartphones on MediaTek (Redmi 9, POCO M3 et al.: Enter the code: ##36446337## → Go to Battery Information.

In the engineering menu you will see the advanced data:

🔹 If Battery Health: Poor is displayed in the engineering menu (50% or lower), the battery needs to be replaced immediately - it can swell or fail at any time.

Method 3: AccuBattery application (most accurate method)

Standard MIUI tools often hide the actual wear of the battery, and for an objective assessment, we recommend using the AccuBattery app (available on Google Play), which analyzes charging cycles and shows real capacity in milliamp hours (mAh).

How to use:

1. Install AccuBattery and provide all the permissions requested.
2. Charge your phone to 100% and use it normally to a discharge of up to 15-20%.
3. Go to the Health tab, where the current battery capacity will be displayed.

📌 How to interpret the results:

• 🟢 90-100% of the original capacity – battery in excellent condition.
• 🟡 80-89% – noticeable wear and tear, but the phone will still serve.
• 🔴 Below 80% - critical wear and tear, it's time to think about replacing.

⚠️ Note: AccuBattery only shows accurate data after 3-5 full charge cycles!

Method 4: Checking through ADB (for advanced users)

If standard methods don’t work (e.g., the POCO F4 GT or Xiaomi 13 Ultra), you can use the ADB (Android Debug Bridge) method, which requires a computer but provides the most accurate data.

Instructions:

1. Turn on Developer Mode on your phone: go to Settings → About Phone and click on MIUI Version 7 times.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC, install ADB Tools, and execute the command:

adb shell dumpsys battery

In the conclusion, find the lines:

• Health: 2 - battery in good condition (2 = Good).
• Capacity: 3800 is the current capacity in mAh (compare with passport capacity).
• Voltage: 4200 - Microvolt voltage (divided by 1000).

🔹 Decoding example: If your Redmi Note 11 should have a capacity of 5000 mAh, and ADB capacity: 3500, wear is 30% - this is a critical indicator.

Method 5: Integrated MIUI diagnostics (for new models)

Starting with MIUI 13, Xiaomi added a hidden utility to test the battery to open it:

1. Go to Settings. → The phone.
2. Click 5 times in a row on the kernel version (or MIUI version if the first option didn’t work).
3. Diagnostics menu will appear → Choose Battery Test.

The system will check:

• 🔋 Capacity (% of reference).
• ⚡ Charging speed (if the adapter is connected).
• 📉 Degradation (number of complete charging cycles).

⚠️ Note: Some firmware (e.g. global) MIUI 14.0.4) This test can show inflated capacitance values.

Method 6: Visual inspection of the battery (if the phone is collapsible)

If you're ready to disassemble the phone (like the Redmi 9A or the POCO X3 NFC), you can visually assess the battery condition.

• 🔺 Bloating – the battery bulges, presses on the screen or back cover.
• 🟤 Spots or corrosion on contacts.
• 🔥 The smell of burning is a sign of an internal short circuit.
• 📏 Deformation – the battery is not flat, but curved.

🚨 Critical hazard: If the battery is swelling - immediately turn off the phone and don't try to charge it! risk of fire or explosion!

To replace, use only the original Xiaomi batteries labeled MB- (for example, MB-40 for the Redmi Note 10). Cheap counterparts can not only quickly fail, but also damage the power controller.

Method 7: Online Services (for IMEI verification)

Some sites offer IMEI battery status checks, but this method is not reliable.

• 🔍 Databases are rarely updated (information may be outdated).
• 🔒 Xiaomi does not transfer battery data to open registries.
• 💳 These services often require payment for a “full report".

If you still want to try it,

1. Find out your phone's IMEI: *#06#
2. Enter it on sites like IMEI.info or IMEI24.
3. Check the Battery Status section (if you have one).

⚠️ Note: No online service will show actual battery wear, maximum date of battery production (if any) ADB.

💡

The only reliable way to check the battery IMEI — You can contact Xiaomi with a check to buy it, and they can provide data from the internal database.
